Source of Individual Differences in Digit Span.

摘要

Individual differences in the ordered recall of list of digits are examined experimentally. The resulting evidence argues that neither differences in rehearsal strategies nor differences in the tendency to group and chunk the digits are major determinants of differences in digit span size. Further experiments attempt to pinpoint the source of individual differences in the sequence of basic information processes hypothesized to underlie performance on the task. The results implicate early processing stages.
